SPECIFICATION forming part of Letters Patent No. 369,542, dated September 6, 1887.

Application filed September 18, 1886. Serial No.213,882. (l\'o model.)

To all whom it may concern.-

Be it known that I, WILLIAM J. MARTIN, a citizen of the United States, residing at Oatawissa, in the county of Columbia and State of Pennsylvania, have invented certain new and useful Improvements in Dust-Oonveyers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has for its object to provide chine, which may be of the ordinary or any approved construction.

B indicates the conveyer, which consists of a rectangular boX or casing, 0, having a flaring base, 1), open at the bottom and adapted to fit upon tlie top of the thrashing-machine, as shown in Fig. l of the drawings, the casing being provided with an exhaust-fan, E. The casing F of said fan sets in the lower half of the casing B, which is provided with spaces at each side of the fan-casing F, forming passages communicating with the central openings of the fan-easing, through which the dust is drawn from the thrashing-machine into said fan-casing by the draft created by the fan.

From the casin g B extends a spout, G, through which the dust is discharged. The said spout fits over a flange, H, at the discharge-opening of the fan-casing, and is secured to the casing B by means of the hooks and staples K. The fan-shaft extends through both casings, and on one projecting end is provided with a pulley, L, by means of which the fan may be driven by a belt connected with the driving pulley or wheel of a suitable motor.

By disengaging the hooks M from their staples and lifting off the top or easing 0 access can be had to the interior of the machine.

As the top of the outer casing may be removed as well as the fan-casing, it is evident that the parts may be readily and conveniently cleaned or repaired when necessary.

It will be observed that not only the casing G is removable from the inclined portion B,

from the casing 0.

Having thus described my invention, what I claim, and desire to secure by LettersPatent, 1s-

The within described dust conveyer for thrashing-machines, consisting of a rectangular box, (1, and a flaring base, D, detachably secured together, a fan-case provided with an exhaust-fan, and a conveyer-spout detachably secured to the discharge of the fan-case and easing O, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM J. MARTIN.
